Stronghold & Key Hunt Guide — 100 Days At Sea

What Is the Stronghold?

The Stronghold is a mid-game objective referenced in community gameplay — a fortified location or structure unlocked with a Stronghold Key found through exploration or island chest drops. YouTube creators describe searching for the key while defending against pirate raids on an expanding raft.

Stranded Devs has not listed Stronghold on the official Roblox game page description as of July 2026. Treat location coordinates and exact key drop rates as community reports, not verified wiki facts.

Stronghold content sits between early Starter/Jungle farming and late-game Volcano/Ice boss progression — roughly Days 15–35 in typical pacing per survive day 100.

Stronghold Key Hunt — Community Steps

Step 1: Expand your raft with Raft Expansion and Container Shelter before long exploration sails — pirate raids punish underbuilt bases per raft building.

Step 2: Farm Desert Island and Shipwreck Island for Iron, Gunpowder, and ranged weapons — Sand Worm and Ghost Captain prep overlaps stronghold mid-game.

Step 3: Search island chests and exploration points for key drops — Treasure Hunter class (+25% chest loot) accelerates key hunts on tier list.

Step 4: Coordinate co-op — one player maintains raft defenses while others scout island interiors per co op strategy.

Step 5: Unlock the Stronghold when the key appears in inventory — community footage suggests unique loot or progression unlock inside; we update when verified.

Pirate Raids During Key Hunts

Pirate attacks interrupt stronghold runs in community videos — same night-invasion family as standard raft defense but with pirate-themed boarders.

Flintlock Pistol minimum; Cowboy Revolver or Sharpshooter Scoped Rifle preferred for deck clearance.

Stock Medkits before leaving dock — failed stronghold attempts in Eld & Dad footage stem from hunger plus simultaneous pirate pressure.
